There are many irrigation ponds for agriculture in Setouchi area. Photosynthesis of algae may contribute to the absorption of carbon dioxide, while sediment in the bottom of ponds may contribute to the emission of methane under anaerobic environment. In this study, we observed carbon dioxide and methane gas exchanges over a pond by eddy covariance method in Kakogawa city, Hyogo prefecture. We analyzed the relationship between greenhouse gas dynamics and environmental factors to elucidate the mechanism regulating greenhouse gas dynamics in the pond.
